23 THE HAYSTACK Price Paid vs. HPI Average

The below graph shows the average detached house price in the West Northamptonshire local authority area over time, sourced from the HPI. The four 23 THE HAYSTACK sales between July 2004 and July 2025 have been plotted on the graph. A line has been extrapolated to show what the value of the property might have been over time, following each sale, had it maintained the same margin above or below the HPI (as a percentage). For example, the November 2014 sale was for 1% below the HPI. So the extrapolation line tracks at 1% below the HPI over time, until the July 2025 sale, where it falls to 4% below the HPI. The line then continues to track at 4% below the HPI.

What might 23 THE HAYSTACK be worth now?

This is based on house price inflation of 1.2%, between July 2025 and April 2026, for detached houses, in the West Northamptonshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 1.2% inflationary increase is applied to the most recent sale price for 23 THE HAYSTACK of £450,000 on 31st July 2025. For the value to have increased from £450,000 to £455,530 over the one year and three months to April 2026, the following assumptions must hold true:

• The July 2025 sale price of £450,000 represented a fair market value for the property.
